Granted: 1996-02-27
Abstract: A coaxial cable comprises an inner conductor consisting of a very fine metal wire having a diameter of 120 µm or below and a tensile strength of 100 kg/mm or above, and a plated noble metal layer coating the very fine metal wire, an insulating layer of an insulating material coating the inner conductor, an outer conductor coating the insulating layer, and a jacket coating the outer conductor.  In forming the inner conductor, a metal wire is coated with a noble metal layer by plating, and then the metal Wire coated with the noble metal layer is subjected to plastic working to reduce the diameter and to improve the structure of the noble metal layer.  A high-frequency signal applied to the coaxial cable is transmitted through the noble metal layer of a satis-factory structure by skin effect without being disturbed.  The very small diameter and very high tensile strength of the very fine metal wire of the inner conductor enables the coaxial cable to be formed in a very small diameter.   Such performance and structure of the coaxial cable is advantageous in its application to electronic equipment in-cluding IC chip testers and high-speed electronic computer systems.

Title: Clip for securing lens elements in light fixtures
Inventor: TAYLOR GRAHAM W
IPC: F21V17/16
Filed: 1991-08-21
Granted: 1994-08-02
Abstract: ABSTRACT OF THE DISCLOSURE         A retaining clip is shown which is used to secure a lens element within a light fixture during a dislodging event, such as an earthquake or contact with a person or object.    This clip protects persons below from injury by the falling lens element or by falling glass, should the lens element or the light bulbs become broken during the event.  The clip includes a jaw portion which securely fastens the clip to the light fixture and a tail portion which provides a flattened surface on which the lens rests and a downturned portion to facilitate removal of the clips from the light fixture.  The upper jaw and tail portion effectively create an extension of the frame to provide a wider ledge on which the lens may then rest.  No tools are required for the installation or removal of the clips, and the clips are easily removed from the light fixtures for replacement of bulbs or for other maintenance.

Title: Metal halide discharge lamp with defined shank loading factor
Inventor: THOMAS BRIAN J
IPC: H01J61/30
Filed: 1991-12-30
Granted: 2002-08-13
Abstract: A low-wattage metal-halide discharge lamp (10) has a quartz tube (12) of the double-ended type that forms a bulb (14) or envelope, a pair of electrodes, e.g., an anode (30) and a cathode (32), which penetrate into an arc chamber (16) inside the envelope (14), and a suitable amount of mercury plus one or more metal halide salts. The electrodes (30, 31) are each formed of a refractory metal, i.e., tungsten wire, extending through the respective necks (22, 24) into the arc chamber (16). Heat dissipation through the neck (22, 24) is controlled by constructing the quartz shanks (26, 28) so that they have shank segments of a desired surface area that ex-tend from the necks (22, 24) a distance equal to the length (50) of the arc chamber (16). A shank segment loading factor is defined as the rated power divided by the shank segment surface areas, and should be in a target range of 12 to 36 w/cm2. Lamps of this design achieve high efficacy at relatively low power, i.e., below 30 watts.

Title: Radio paging system having a plurality of transmitter stations
Inventor: ICHIKAWA YOSHIO
IPC: H04H20/67
Filed: 1993-01-11
Granted: 1998-04-14
Abstract: A global radio paging system is disclosed in which a plurality of radio frequency carriers having the same frequency are synchronously modulated in a plurality of base stations, corresponding in number to the radio frequency carriers with the same digital paging signal, and are then transmitted. A pagingcontroller which receives paging calls through a public switched telephone network stores preliminarily the maximum value of a sum of a paging request signal transmission time in a transmission line and a time required to process the paging request signal in each of the base stations and a high precision time signal is produced on the basis of a reference signal from a GPS (Global Positioning System) satellite. In this paging controller, a transmission time assigning code is attached to the paging request signal. The transmission assigning code assigns a transmission start time which is delayed from a currenttime determined by the high precision time signal by the maximum value of the sum of the transmission time and the processing time. On the other hand, in each of the base stations, a high precision time signal is produced on the basisof the reference time signal from the GPS satellite and the paging request signal supplied through the transmission line is processed on the basis of the high precision time signal to convert a format into the digital paging signal to thereby realize synchronous modulation of the carriers.

Title: Process and apparatus for control of multistage catalyst regeneration with partial co combustion
Inventor: OWEN HARTLEY
IPC: F27B15/00
Filed: 1991-07-11
Granted: 2001-10-16
Abstract: A process and apparatus (Figs. 1,2,3 and 4) for con-trolled, multi-stage regeneration of FCC catalyst is dis-closed. A modified high-efficiency catalyst regenerator (80), with a fast fluidized bed coke combustor (62), dilute phase transport riser (83), and second fluidized bed (82) regener-ates the catalyst in at least two stages. The primary stage of regeneration is in the coke combustor (62). Second stage ca-talyst regeneration occurs in the second fluidized bed (82).      The amount of combustion air added to both regeneration stages is set to maintain partial CO combustion in both stages. Controlled multi-stage regeneration reduces the steaming or deactivation of catalyst during regeneration, maximizes coke burning capacity of the regenerator (80), and minimizes or eliminates NOx emissions.

Abstract: A multi-functional, universal guide rail member is provided, for incorporation in an architectural joint system.  Typically, one such guide rail member is mounted on each of two adjacent, relatively movable structures and cooperates  with  pivotally  mounted  centering  bars  to maintain a covering plate in centered position.  The guide rail member incorporates in a single,  integral unit a continuous guide groove for the centering bars, an open-sided slot for receiving fastening means  (or,  in some cases,  caulking),  and  an  outwardly  facing  slot  for receiving anchoring means.  The multi-functional guide rail member is usefully employed in conjunction with standard off-the-shelf structural components, such as channels and angle members, to accommodate mounting of the guide rail members in a variety of architectural configurations.  In some architectural joint systems the multi-functional guide rail members may be employed in a manner making use of less than all of their functions, adding to the universality and economy of the system.

On the other hand, when the pointing device is set upside down by the user, ball 10 moves to the opposite side via gravitation.  Then ball 10 is inserted between stopper 8 and keyboard 1 and, as a result, keyboard 1 is fixed by ball 10. When the user spins ball 6, the ball moves in all directions in accordance with the user's operation.  Furthermore, when the user pushes coordinate converting unit 4, detecting switch 7 is pressed by protrusion 3, and then detecting  switch 7 is switched to the ON state.
